Holy crap these responses are hilarious. Slick, please take information at face value. Like many have said, at the end of the day we can't stop you from filling the tires with maximum pressure.

That being said the manufacturer recommends the pressure on weight of vehicle and regular driving conditions. Unless towing or anything out of the ordinary I would highly recommend following the door jam sticker. Unless you desire wearing your tires irregularly/uneavenly there isn't much benefit to going outside this range.

"Fuel efficiency" isn't worth the trade off for tire life when you over-inflate and "comfort" when under-inflating will do just as much damage. One of the most common reasons for premature tire failure is improper tire pressure. Anyone who has ever run a shop or been around them (myself included) would concur.
his was high from dealer so he asked his question. hes now at 36lbs. what will happen from 33 to 36lbs?

If someone posts nonsense on the internet- especially to a group of people with pertinent knowledge- they better grow a thick skin or stop revealing their ignorance. A few extra lbs of pressure isn't a big deal. In fact a slight increase in pressure (regardless of some comments on this thread) will add a bit more tire life at the expense of ride quality. Bear in mind that the suggested pressures are "cold" pressures. A tire in the summer driven down the road will easily add 3-4 psi.

Another vote for 38 cold 40 hot
I was wondering why she road so hard !!
To much air 46 was not the way to go and just think I’ve been riding her like that for 748 miles that’s how many miles that’s on her !!!
Very happy I changed up she roles smooth now !! I’m a believer, thanks for everyone’s input and brainstorming with me I knew something was wrong :)

The Op was super cool about everything. its just me I dont like the way people have no common respect. knowing 100% in real life it would be way different. I also didnt see anyone make any nonsense posts other than the guys saying you have to run 33 psi its a recommendation thats it his 36 will be just fine.

I do believe you that the tire will gain 3-4lbs but its summer here its been 100 and mine only goto 40lbs I have them at 38 cold. this is city traffic, about how long will it take to go up 3-4 lbs? Im more curious its not like I am gonna lower it just want to know.

It depends on what you consider "cold"! Had you put 38 psi in at say 70 degrees, with tires at that same temp, at 100 degrees outside you'd see a definite increase. Pretty hard to predict some exact amount of pressure increase without knowledge of the exact amount of temperature rise. Just run whatever psi you're comfortable with. It should definitely be at least at 33, and I would stay well away from the peak pressure. Somewhere in between is fine. I keep mine at 35-36 and couldn't care less what others might think about that choice! Probably more important that all four are with a psi or two.

Heck, people can run these tires backward and no one else would care. The fact is many people would never feel/see the difference. That's the thing about buying a car, the tires are yours, use as you see fit. The whole point of any of these threads is to share good information, hopefully, it's accurate. I usually don't see comments like some posted in this thread unless it's an oil change thread. :rolleyes:

Or a 3 bolt vs 4 bolt thread!

Ha cold really isn’t cold here in Ca what ever my garage temp was prob 80 but like clock work everyday it goes from 38 to 40.
inwas more just curious not a huge deal.
I also don’t care if someone thinks my 38 is to high. This isn’t my first set of tires won’t be my last either I’ve never had a issue with tires other then nails lol.

lol do you swallow also?
you run 33psi oh big deal. take your Im better then you attitude
The OP will figure out what he wants to run and big deal. its a recommendation not a law. I think he said hes running 36lbs lol you think the tire is gonna blow up or something? you think your better cuz you have 3lbs less than him? what do you think will happen to his tire at 36lbs? I gotta hear this.
Well I hope your vulgar replay makes you feel better and proves how smart you are.
his was high from dealer so he asked his question. hes now at 36lbs. what will happen from 33 to 36lbs?
I replied to that more than once as to why. How many times did you try to help?

Lol you never replied to what will happen from 33 to 36. That’s the only question in there so you prob should question how smart I am.

Unless someone were able to run an A -B comparison under the exact same conditions no one with certainty can say what the difference of 3 lbs. pressure difference over the life of the tire may actually do.

There are "gives" and "takes" in performance, mileage, tire life, performance, braking, etc. In theory that is what Ford is to have determined and why they specify a particular recommendation. It's what they have determined to be the best compromise of all worlds.

You can add a few pounds to a tire and perhaps get a little better mileage, tire life may suffer, you can both overinflate and underinflate and reduce braking ability, and the list goes on.

I'm happy to listen to anyone that has had the opportunity to put two identical Exploders through the paces with different pressures and identical conditions over the lives of the tires. I'll be interested when you report back on how they handled over the life of the tire. Of course, you'll need to have access to a skid pad, a driving range, braking pad, and drag strip... well you know what I'm saying.

This is a pretty good read:

I did question your intelligence. And I replied as to why his tires came over inflated. I also posted the article from Car and Driver where they went into detail the reasons why a person should run the recommended PSI.

Not anything you would notice. Cold pressure is just ambient air when car hasn't been driven recently. So if you're in hotter climate then when the tires were initially filled up that could be part of the issue.

Used to see problem all the time in the winter when customer cars would come into the shop. Heated shop and car would sit for a while, we'd adjust air pressure and then next day car would sit overnight and when started the TPMS light would pop on and they would think we did something wrong.

As long as you keep it close to the sticker, normal driving it will rise, etc. you will be fine. Just not 50...lol

Thank you for reply. I was asking knowing the idiot Dale couldn't answer no one can 33 to 36 prob would be zero difference def not worth Pirelli or any tire makers time to find out.
Its not cold or hot enough here to see drastic changes in pressure. most of my cars are in garage but I only seen it raise 1lb today it was only a 14 min drive but I drove it hard on purpose to see if I could get it to change any more.

Her is a legit question just because you seem to know about tires. what will happen if you drive it at 50lbs? it might be harsher ride? tire might wear in the middle a little faster? if it wears faster what's a educated guess 2k miles faster to need new tires? what is the tire rated at 45K miles?

Sorry I was asking a question I knew no one could answer. it was to prove a point to anyone that there is no difference between 33 to 36. Your reply took time and I appreciate anyone taking their time to reply with out being an internet bully.

If you were to constantly drive with your tires inflated to 50 psi, I would expect you to cut the total mileage in half. Even a slight misalignment could ruin your tires in a few thousand miles. You would notice it pretty quickly.

Well i picked it up from the dealership with 48 psi I was wondering why they deliver them with such high tire pressure !!
My explorer was riding like a basketball not kidding you !!!
I’m glad I asked the question I was a bit confused I feel like I’m on the rite path now after reading all the responses !!
Thanks everyone:)

You sir are a good dude. I was ready to fight all these weirdos and you just cruise thru like a pimp, lol I wish I had your composure.
I might pump my tires up to 48 just to see how different it is.
I did learn that my tires from cold to hot only raise 2lbs I always knew they did but never how much. I still need to get on freeway for a longer trip to see if its more. Kinda useless info but still info,lol. Have a great weekend.

I do 38psi so warm its closer to 40psi
Look on your tire that's the best place to get info.
No offense to Dale but what if you bought used and they had swapped tires or what if the dealer swapped tires? dont look at the door or owners manual. Look at the actual tire on the car.
There's nothing on the tire that contains valid information. The door placard is the source.
